SPECIFICATION forming part of Letters Patent No. 373,023, dated November 8, 1887. Application filed March 1, 1884. Serial No. 122,708. (No model.) A

To all whom it may concern.-

Be it known that I, CONRAD KAHLER, residing at Chicago, inthe county of Cook and CState of Illinois, and a citizen of the United States, have invented certain new and useful Improvements in Rotary Printing-lvlachines,

papers or sheets after they are severed, showing also in outline the delivery printing-cylinder and the receiving end of a folder; Figs.

4, 5, 6, 7, and 8, details in outline showing the arrangement of the electrotype-plates of the printing-cylinders for printing, respectively, twenty-four, twelve, eight, six, and four page papers; Figs. 9, 10, 11, 12, and 13, details showing the arrangement of the pages, respectively, for a twenty-four, twelve, eight, six, and four page paper as printed with the arrangement of plates shown on the printingcylinders; Fig. 14, an outline showing the manner of running the continuous set of tapes over the folding-rollers for folding a twentyfour or eight page paper. Fig. 15 is a vertical longitudinal section through one of the cutting-cylinders.

The object of this invention is to construct a press on which four, six, eight, twelve, or twenty-four page papers or sheets can be printed, as maybe desired, and after being printed delivered to cutting-rollers and severed in a proper manner into separate papers orsheets ready for delivery to a folder to be folded into proper shape for handling; and its nature consists in the several devices and combinations of devices hereinafter described, and specifically pointed out in the claims, as new for attaining the objectsought.

In the drawings, Arepresents the first type or form cylinder, consisting in the form of construction shown of a cylindrical shell having at each end a center or hub,with radial arms or spokes joining the hub, with the shell, through which centers orhubs the supportingshaft passes,which shaft, through the medium of suitable gearing, drives the cylinderat the proper rotation. The periphery or exterior face of this cylinder A is divided, as shown, by a partition or flange, A, into two halves or end sections, and each of such sections in use has secured thereon, by suitable dovetailed flanges, as shown in Fig. 2, or in any other suitable manner, the electrotype-plates from which the impression is to be taken, each section in the form of arrangement shown having six plates, a a a a a a B represents the second type or form cylin- 'der, located at the proper distance from the cylinder A for interposition of the'blanket or impression cylinders and the passage of the web or sheet of continuous paper from the cylinder A to the cylinder B, and this cylinder Bis similar in construction and is mounted and operated in the same manner as the cylin- 7c der A, except in having a reverse rotation given to it. The periphery or exterior face ofthis cylinder B is divided by a partition or flange, B,.into two halves or end sections, and each of such sectionsin use has secured thereon, by suitable dovetailed flanges, as shown in Fig. 2, or by other suitablemeans, a series of electrotype-plates, b b b b b If, from which the impressions are to be taken, which plates respectively coincide or back the plates to a a a e c on the cylinder A. The series of plates on these cylinders A B contain the matter to be printed on the papers or sheets, and the manner of arranging these plates to print a four, six, eight, twelve, or twenty'four page paper or sheet will be hereinafter described.

0 is the blanket or pressure cylinder which coacts with the cylinder A to hold the paper to the electrotype-plates, the cylinder having a blanket, c, secured thereon in the usual manner, which blanket may be ofthe material ordinarily used for this purpose.

D is the blanket or pressure cylinder coacting with the cylinder B to hold the paper to the electrotype-plates,'this pressure-cylinder having a blanket, d, corresponding to the blanket c of the cylinder 0.

E represents the ink-distributing rollers, one at each end of the press, to supply the ink to the respective inking-rollers of the printing-cylinders A B, the ink being transferred to the plateson the respective cylinders through the medium of smaller rollers, e, as shown in Fig. 2, or otherwise.

F represents the ink-troughs, one at each end of the press, and each having a take-up roller, F, by which the ink is raised from the trough, and through the roller f transferred to the roller E. The rollerfis suspended by suitable arms, f, from a shaft,f, which shaft is supported in uprights or standards f, extending up from the main frame, as shown in Fig. 2.

G is a cutting-cylinder, consisting of a cylindrical shell having at each end a center or hub, with radial arms or spokes connecting the shell with the hub. This cylinder is mounted on a shaft, the ends of which are supported in suitable journal-boxes on the main frame, and the cylinder is so located in relation to the second or delivery printing-cylinder, B, as that the continuous sheet of paper as printed will pass from the cylinderB to the cylinder G. As shown, the cylinders B and G are arranged for the paper to pass in a slightly-diagonal direction; but they could be arranged to have the paper pass in a vertical line or otherwise. This cylinder G is provided with three outting-blades, g, and a corresponding number of slots, 9, a slot lying adjacent to each knife or blade, as shown in Fig. 3. The cutting-blades are each mounted in a frame or box, 9', and at each end of each blade is a set-screw, g, which passes through the head of the cylinder or through the arms or spokes, so as to bite against the end of the blade or cutter and hold it in either a projected or withdrawn position, accordingly as the blades are to be acting or non-acting, by which arrangement all three of the blades can be brought into use, or any two of them, or only one. Each blade passes through a head or block, 9', set in the periphery of the cylinder, and these heads or blocks also form the matrices g for the cuttingblade of the other cutting-cylinder, and the knives or cutting-blades and the matrices on this cylinder G are arranged to have the dis tauce between them the same as the space of a single electrotype or plate on the cylinders A H is the other cutting-cylinder, also consisting, as shown, of an exterior casing or shell, having at each end a center or hub, with radial arms connecting the rim and the centers or hubs. This cylinder is mounted on a shaft suitably journaled on the main frame of the machine, and this cylinder and the cylinder G are to be rotated through suitable gearing. The cylinder H is of smaller diameter than the diameter of the cylinder G, and its periphery is provided with two slotted blocks or heads, h, arranged on opposite sides of the cylinder and in line with each other, which heads or blocks form the matrices for the blades of the cylinder G, and one of these slotted blocks or heads h has arranged therein a cutting-blade or knife, 7z,which can be held in a projected or withdrawn position in the same manner as the blades 9, so as to be acting or non-acting.

The blades 9 eoact with the matrices h, and the blade h coacts with the matrices g to sever the papers or sheets from the continuous sheet, and the manner of setting the blades, as required for cutting the different-paged papers, will be hereinafter described. The circumference of the cylinder H corresponds to the space occupied by two of the plates of the printingcylinder, so that each revolution of the cylinder H will separate the continuous web or sheet at the proper point for the width of two plates, forming two pages of the paper or sheet.

I I, J J, K K K, L L L represent each a roller or series of pulleys, and each mounted on a suitable shaft supported in hearings on the frame of the machine. The roller I is located adjacent to the cutting-cylinders, and from this roller, around the rollers or pulleys J K, and out over the roller or pulleys K, around the pulleys K,and back under the pulleys I, a single set of tapes, z, leads, and from the roller or pulleys L, out and around thepulleys L, and up and over the roller or pulleys L, a series of tapes, j, leads.

M is a switch mounted on a shaft, M, supported in hearings on the frame, which shaft is rocked by an arm. l\ and a rod, M", from a running part of the press. This switch is formed of curved arms m on each side of a cen tral point,whicl1 point lies in the angle formed by the peripheries of the rollers or pulleys J K, and the switch acts to turn the leading edge of the section or sheet carried by the tapes 2' around the roller or pulleys J,'or around the roller or pulleys K. v

N N represent each a roller or series of pulleys, and each mounted on a shaft supported in hearings on the frame of the machine, and over these rollers or pulleys a series of tapes, a, run just above the tapes i, for the purpose of holding the paper down at this point to be carried by the tapes, and the paper is supported between the pulleys J J by an upper series of rods, in, and a lower series of rods, which rods form, in connection with the tapes 1', a pathway for the travel of the paper.

The parts represented by the letters I I, J J, K K K, L L L, M M M, N and N, and z, j, 7c, 70, Z, m, and it constitute a sheet-delivery device,which is made the subject-matter of a separate application filed July 17, 1885, Serial No. 171,885, and therefore their construction and operation are not herein specifically described, and such parts are only here shown for the purpose of illustrating a delivery of the sheets after being severed.

0 represents the base of the frame of the machine, 0 standards or posts, and O the top of the frame, which parts for each side may be cast in one piece, or they may be formed of separate pieces suitably secured together, and they may be of the form and arrangement shown, or any other form that will furnish a support for the acting parts of the press and paper-delivering devices.

P represents journal-boxes supporting the I are secured to the printing-cyli nd'ers with their columnrules running parallel with the length of the cylinder instead of running around transversely. The electrotype 7 plates, as shown, are arranged to have six plates on each'end section or'half of each cylinder, making twelve plates to each cylinder, or twentyfour in all, and from this arrangement of plates a four, siX, eight, twelve, or twenty-four page paper or sheet can be printed. A twentyfourpage paper is printed when the plates are arranged as shown in Fig. 4, in which arrangement the cylinder A prints the outside pages and the cylinder B the inside pages, and for printinga twenty-four-page paper the electrotypes a a, a" a a a on one half of the cylinder A will contain the matter, respectively, for pages 20, 5, 22, 3, 24, and 1, and the corresponding electrotypes on the other half of the cylinder will have thereon the matter for pages 17, 8, 15, 10, 13, and 12, pages 20 and 17 being the leading ones, or those first printed, and the others following in succession as named. The cylinder B, assuming that the travel around cylinders O D is equal to the space occupied by three electroplates in the cylinders A B, will have on its section or half corresponding to the first section or half of the cylinder A the matter for pages 4, 23, 2, 19,

23, and 21, and its other half or section will have on its electrotypes the matter for pages 9, 14, 11, 18, 7, and 16, pages 4 and 9 being the leading ones, or those first printed, and the other pages following successively in the order named, so that page 20 will. be backed by 19, 5 by 6, 22 by 21, and so on, and page 17 will be backed by 18, 8 by 7, 15 by 16, 10 by 9, and so on.

' were printed in one continuous sheet the pages would be arranged as shown in Fig. 9, and

when so arranged the head of each page would be at the center, as shown by the numerals on Fig. 9, which figure represents the two sides of the paper, the lower diagram of the figure representing the side printed on the two end sections of cylinder A, and the upper diagram the face or side printed on the two end sections of cylinder B, so that one diagram represents the other turned over and shows the backing-numbers of the pages. It will be understood, too, that the two cylinders A and B will be so placed relativelyto each other as to allow for the distance that the web If a twenty-l'our-page paper must travel from cylinder Ato cylinder B and bring the right backing-number'in itsproper place-that is, for illustration, so that page 19 will back page 20.

The plates for printing a twelve-page paper or sheet are arranged as shown in Fig. 5, the plates on one end section or half of the cylinder having thereon the matter for pages 8, 5, 10, 3,-12, and *1 of the paper, and the corre sponding plates on the other end section or half of this cylinder having thereon the matter to duplicate these same pages on apaper, but in different order, as shown in the lower diagram of the figure, and the plates on the half or .end' section of the cylinder B corresponding to the first end section of the cylinder A have thereon the matter for pages 4, 11, 2, 7, 6, and 9,-which matter is also duplicated on the corresponding plates of the other half or end section of this cylinder, but in difterent order, as shown, so that with each revolution of the cylinders two complete twelve-page papers will be printed, pages 8 and 5 being the leading ones on the cylinder A, and pages 4 and 9 on the cylinder B, the pages of the two cylinders, respectively, backing each other in the order named, and the product of this arrangement of plates for a twelvepage paper, if

printed in a continuous sheet andnot subdivided, would be as shown in Fig. 10.

The plates for printing an eight-page paper are arranged on the cylinders as shown in Fig. 6., The plates on one end section or half of the cylinder A have thereon the matter to print pages 8 and 1 of three papers, and the plates on the other end section or half of this cylinder have thereon the matter for printing pages 5 and 4 of three papers, and the plates on the end section or half of the cylinder B corresponding to the first half of the cylinder have thereon the matter for printing pages 7 and2- of three papers, the other half or section of this cylinder having on its plates the matter for printing pages 6 and 3 of three papers, so that with each complete revolution of the cylinders three complete papers will be printed, and the product of this arrangement ol'plates, if printed in a continuous sheet, would be as shown in Fig. 11. The plates are arranged to have pages 8 and 5 the leading ones of the cylinder A, and 2 and 3 of the cylinder B.

The plates for printing a six-page paper are arranged on the cylinders as shown in Fig. 7, the plates on one end or half section of the cylinder A having thereon the matter for cylinder has on its plates the matter for print- 1 ing-pages 4, 2, and 5 of two papers, so that at each revolution of the printing-cylinders four complete six-page papers will be printed, and

the product of this arrangement, if printed in a continuous sheet, would be as shown in Fig. 12. The leading pages of the cylinder A are 4 and 3 and of cylinder B are 3 and 4.

The plates for printing a four-page paper are arranged on the cylinders as shown in Fig. 8, the plates on one end section or half of the cylinder A having thereon the matter for printing pages 4 and l of three papers, and the corresponding plates of the other end section or half of this cylinder having matter to print pages 1 and 4 of three other papers. The plates on the end section or half of the cylinder 13 corresponding to the first half of the cylinder A have thereon the matter for printing pages 3 and 2 of three papers, and the other end section or half of this cylinder has its plates with matter thereon to print pages 2 and 3 of three other papers, so that with each complete revolution of the printing-cylinders six complete four-page papers will be printed, and the product of this arrangement, if'made in a continuous sheet, would be as shown in Fig. 13. The leading pages of the cylinder A are 4 and 1 and of cylinder B 2 and 3.

The cutting-cylinders for separating or dividing the sections of a twenty four or a twelve or dividing an eight or a four page paper are arranged to have the cutting-blades of the cylinder 0 withdrawn and the cuttingblade of the cylinder H projected, in which position a single revolution of the cutting-cylinder H divides or separates the continuous sheet or web into sections corresponding to one-third of the circumference of the formcylinders, each section containing the matter of two consecutive plates on the form-cylinders, and for dividing or separating a six-page paper the knife on the cylinder H is withdrawn and two of the knives on the cylinders G projected, so as to divide or separate the continuous web into long and short sections alternately, the long sections covering the space occupied by two consecutive plates on the form-cylinders, and the short the space occupied by one plate on the form-cylinders.

In operation, with the plates arranged to print a twenty-four-page paper, in which case the cylinder H will be the male cuttingcylinder, the continuous paper or web as printed will pass from the delivery printing-cylinder B between the cuttingcylinders G and H and will be partly divided or separated by the blade or knife of the cylinder H transversely at a point containing the matter of two consecutive plates, and the succeeding sections, containing the matteroftwo consecutive plates, will be successively divided by the action of these cutting-cylindersG H until the product of the press has been divided. The manner of disposing of the product thus produced by the tapes 1 and the delivery devices coacting therewith is fully set forth in the specification for these parts filed July 17, 1885, Serial No. 171,885. Three sections as divided by the cutting cylinders are required to make a twenty-four-page paper, each section containing eight pages.

The continuous web of paper, if of suificient width to extend across the printing-cylinders in printing a twelve-page paper, will have to be slitted longitudinally at the center as a paper is printed on each half or end section of the printing cylinders, and the continuous web, after being printed on, passes from the delivery printing-cylinder to the cutting-cylinders in the same manner as for a twenty-fourpage paper, except in belng in two sections instead of one, which are carried through the cutting-cylinders and divided into sections by the cutting-blade for delivery to the folder, two papers being delivered simultaneously in the same manner as printed, and the operation is continued until the product of the press has been disposed of.

The continuous web of paper in printing an eight-page paper extends across the cylinders the same as with a twenty-four-page paper and the paper after being printed passes between the cutting-cylinders and is severed into sections, each section containing the matter for afull eight-page paper, and theseparated sections are delivered to the folder by the delivery devices. The continuous web for a six or four page paper, if of sufficient width to extend across the cylinder, is slittcd longitudinally, as the end sections or halves of the printing-cylinders are duplicates one of the other, and for a four-page paper the sections are divided by the cutting-cylinders into sections equal in length to two of the consecutive plates on the printing-cylinder, each section containing the matter of a complete four-page paper.

The cutting'cylinder H is the one used for cutting the papers thus far; but in separating a six-page paper the knife of the cylinder H is withdrawn and two of the knives of the cylinder G projected, in which condition the continuous web will be divided by the action of the knives into short and long sections, the short section being the first or leading one, and this section on each side of the paper as it comes from the printing-cylinders contains pages 3 and 4 of a six-page paper, which short section is to be added to the next succeeding long section, containing pages 1, 6, 2, and 5, and the long section and short section of paper thus brought together make a complete whole, and this operation is continued until the required number of papers has been reached, it being understood that two papers are carried and delivered to the folder simultaneously the same as printed.

The partof the foldershown in Fig. 14 illustrates only the blade and rollers for'making the first fold in a twenty-four or eight page paper, and the parts shown in Fig. 14 are only for the purpose of illustrating a means for taking the paper from the cutting-cylinders, and constitute no part of the present invention, which relates simply to the arrangement of plates and cutting-cylinders for producing papers of varying number of pages, the delivery devices forming the subject-matter of another application, filed July 17,1885, Serial No. 171,885.

By. using two cylinders, G H, either of which may be the male or female, the continuous web is divided into sections, as required for the number of pages for the whole paper, and by combining the printing-cylinders with the cutting-cylinders papers consisting of a varying number of sections can be printed and divided into the required number of sections forthe paper to be delivered to a folder, enabling papers having different number of pages to be printed, divided, and delivered as may be required by the use of asingle press.

The delivery device should be one adapted to deliver twenty-four, twelve, eight, six, and four page papers, to do which the first section, containing pages 7,18, 6, and 19 011 its upper side and pages 8, 17, 5, and 20 on its under side, is to be overlaid on the second section, containing pages 9, 16, 4, and 21, and 10, 15, 3, and 22 on its-upper and under sides, respect- 25 ively, and the two sections are to be overlaid on the third section, containing-pages 11, 14, 2, and 23, and 12, 13,1, and 24 on its upper and under sides, respectively, and the three sections then delivered to the folder or other place of deposit, and for a twelve-page paper the continuous web as divided by the cutting-cylinders has three sections overlaid and delivered as for a twenty-four-page paper, andfor an eight-page paper each-section as divided by the cuttingcylinders contains the whole eight pages, and these sections are each delivered without being overlaid; and the same is true fora four-page paper, and for a six-page paper the short section is overlaid on the long section and the two then delivered to the folder.

What I claim as new, and desire to secure by Letters Patent, is

1. In a printing-press for printing a paper with either four, six, eight, twelve, or twentyfour pages, the pages being the same size in all of said numbers, the combination of cylinder A, having on each side of its centera series of six form-plates, and a .cylinder, B, having on each side of its center a series of six form-plates, the plates of each series hav- 5o ing the column-rules running longitudinally with the length of the cylinders, whereby a paper of the said number'of pages and of the same size may be printed by and on the same two cylinders, substantially as described.

2. The impression or printing cylinders A 13, having impression-plates arranged in series on each of their sides, with the column-rules running parallel with the length of the cylinders, in combination with cuttingcylinders provided with knives which can be projected or withdrawn to act and perforate or partly sever four, six, eight, twelve, or twenty-four page papers or sheets, substantially as described.

3'. The printing-cylinders A B, having on each side of their centers a series of impression-plates, with column rules running parallel with the length of the cylinders, in combination with the cutting-cylinder G, having a series of cutters and matrices, and the cutting-cylind'er'H, having a single cutter and two matrices for separating a continuous sheet after being printed into four, six, eight, twelve, or twenty-four page papers or sheets, substantially as specified.

4. The printing-cylinders AB, each having on each side of its center a series of impression-plates, with column-rules running parallel with the length of the cylinder, and the cutting-cylinders G H, provided with knives which can be projected or withdrawn for dividing the continuous sheet into papers or sheets of various sizes, in combination with delivery-tapes and a switch by which the single papers or sheets, or an accumulated 5 number of papers or sheets, can be carried and delivered to a folding mechanism, substantially as specified.
